Scattering is a general term for several physical processes in which radiation of some sort changes direction due to an interaction with a particle. Scattering can be classified by the type of radiation (ie, electromagnetic, x-ray, neutron), or by the relative sizes of the wave and the particle (ie, ...

I am new to this realm of physics. I have literally understood the matter wave, wave function; read the trapped electron in an infinite potential-well. But what I didn't understand is the concept of ...

It seems that most of the relevant books only give the linear case and the rest say something along the lines of "here are common examples of boundary conditions."
What are the most general boundary ...

I have a question concerning (in my opinion) strange notation that arose in both the book by Shankar and Sakurai in the same manner. Where i am very confused by them both seemingly using the same name ...

Suppose there are three particles, 1, 2, 3. Initially, particle 2 and particle 3 form a bound state. Particle 1 is free. Now we want to study the scattering of particle 1 against the 2-3 bound system. ...

This might be an easy question but I couldn't find it in our course book[Microwave Engineering, Pozar, 4th ed] or on internet.
I have a homework and one of the questions asks me to find the S-Matrix ...

I have a question about how Thomson scattering takes place. Say X-rays hit a bound electron in a crystal. (These electrons aren't "free", but the energy difference is so large that the scattering is ...

I'm trying to solve problem 2.35 in Griffith's Introduction to Quantum Mechanics (2nd edition), but it left me rather confused, so I hope you can help me to understand this a little bit better.
The ...

Let's assume electron-electron scattering in QED in second order of perturbation theory. Then in the corresponding scattering amplitude there will appear photon propagator
$$
D_{\mu \nu}(q = p_{i} - ...

Photon with energy $\hbar\omega$ scattering on a fixed particle with magnetic momentum $\vec{\mu} = \mu \vec s$.
How to calculate a differential and total cross section for the photon.
I've found in ...

In optics and electromagnetics, they frequently calculate the extinction, scattering or absorption cross sections of a single particle (e.g. a sphere). Scattering cross section which is the ratio of ...

Some people say it is bound state, some say it is not. Which is more accurate?
Problem is that I read in some books, including Ziman, that Cooper pairs are bound states but my teacher says that it is ...

Why is the orbit of an alpha particle in the Rutherford gold foil scattering experiment a hyperbola?
The equation of orbit of a two-body system under the influence of gravity ($F_g = -\gamma/r^2$) is ...

What is the scattering angle distribution for x-rays (in the 8keV range) scattered elastically?
I work with XRD analysis, which is fundamentally basede on these elastic scatterings of x-rays. I read ...

In Ryder QFT, regarding the calculation of the scattering amplitude by a weak potential $V$, the potential is assumed to be switched on and off slowly using the adiabatic hypothesis. But there is a ...
